This class provides the guts of a Saxon 6.* implementation of a link unwrapper.

The general design is this: the stylesheets construct a result tree fragment for some environment. Then the result tree fragment is "replayed" through the UnwrapLinksEmitter; the UnwrapLinksEmitter builds a new result tree fragment from this event stream with top-level links unwrapped. That RTF is returned. Note that only a single level of unwrapping is performed. This is clearly a crude implementation.
